MEC 211 - Process Control

 
Description
This course covers the fundamentals of process control and instrumentation as applied in industry for the control of level, flow, temperature and pressure.  The concept of a control loop is introduced and each of the loop’s components are examined:  sensor, controller, final element.  Design, documentation, operation, performance tuning and troubleshooting of single loop systems are discussed.

1. Define process control and key components of operation, function and application.
2. Use common symbols, line types, notations and indexes of a Process and Instrumentation Diagram (P&ID).
3. Operate a loop controller.
4. Connect current to pressure (I/P) converters for final control elements.
5. Adjust a diaphragm actuated proportional valve.
6. Convert between liquid level units, pressure units, sensor output units and display units.
7. Operate ultrasonic level sensors in a closed loop system for level control.
8. Configure electronic controllers to tank level control and alarming using an on/off algorithm and discrete inputs and outputs.
9. Convert between velocity, volumetric and mass flow rate units.
10. Measure flow using orifice plates, venture tubes and pitot tubes together with a differential pressure flow transmitter.
11. Perform thermal energy calculations and conversions between temperature scales, energy units and power units.
12. Connect transmitters for thermocouples, resistive temperature detectors (RTD’s) and thermistors.
